New Site Registration Steps:

Existing Yahoo members, that have made posts, are to use their existing Yahoo ID to log in to the new site.  Since their Yahoo password is a secret it was not converted.  After selecting Login from the top menu, enter your Yahoo ID in the username box and Click on "Forgot your password?".  An email with a temporary password will be sent to the email address associated with the member's Yahoo account (as of the date of conversion).  When the email is received, log in by following the link in the email or by using the temporary password.  Once logged in you can change the password to one of your choice.  If you want a different ID, or if your email address is no longer active, please submit a request for assistance containing your name, Yahoo ID or if you have multiple IDs you want combined, to: ForumHelp@catrvclub.org.
